What to check first
Stop normal operation while this warning is active. Follow only the documented safe checks or protective-drain instructions for the exact model.
Basic checks
- Look for standing water after the cycle stops; if water remains, leave the dishwasher off and skip another cycle.
- Inspect the glass trap and filter only with power off and the tub cool; if food soils are visible, clean them as the model guide describes.
- Reinstall the glass trap and filter exactly as the model guide shows; if either part will not seat normally, stop rather than force it.
- Run one empty rinse or short cycle only after safe cleaning; if i40 returns or water remains, stop and arrange service.
Applicability
Broad appliance guidance · Electrolux dishwashers
Electrolux presents this guidance for dishwashers generally; confirm the exact model guide because filter construction, access, and cycle controls can vary.
Reset or retry steps
- Electrolux says to clean the glass trap and filter, then rerun the dishwasher once; stop if i40 returns.
When to call a technician
- Contact service if i40 returns after the glass trap and filter are cleaned as the model guide describes.

Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
Can I keep using it?
Stop normal use when water is visible or a leak warning is active. Stay clear if water could reach wiring or controls.
- Safe next step
- Follow the code-specific shutdown or protective-drain instructions, turn off water when appropriate, and avoid repeated resets. Do not interrupt a documented protective-drain sequence just to clear the display.
- Stop when
- Water is near wiring, cabinetry is getting wet, the leak returns, or the source is not safely visible.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Stop and address visible water before retrying the appliance.
- Disconnect power before any service-access step.
Do not do this
- Do not continue normal cycles while this code is active; any protective-drain sequence must follow the exact model instructions.
- Do not open drain or pump areas while the appliance is powered.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Food soils built up in the dishwasher sump
- Glass trap or filter clogged with food debris
FAQ

Stop normal operation until the issue and safety warnings have been addressed. Follow only the documented safe checks or protective-drain instructions for your model. Switch off dishwasher power before reaching into the filter area.
When should I call a technician for Electrolux i40?
Contact service if i40 returns after the glass trap and filter are cleaned as the model guide describes. A qualified technician may check Glass trap, Filter, and Drain sump against the model's service information before treating any part as failed.
